Some tree places say to use woodchips / mulch without a weedmat. It keeps the critters out of the mulch. Sort of gives them a nice tunneling area.
Stone might be not needed. I had about 1/2 of a row of plum trees get girdled by voles when I started out doing this. MY real problem was not taking care of the cages with weed control. After spraying weeds 2 or 3 times a year, I 've had zero problems with what I do.
When I mow my nearby foodplot, litterally hundreds of voles come out of the woodwork. Probably kill like 200+ in the 1/2 acre.. I have my backyard area right next to the foodplot. I mow it every 3 weeks or so. No voles in there.
Mine is worth it's weight in gold for your soil. You correct the pH, often the nutrient ratios come out fairly decent.
Your place sound alot better than the typical reclaimed mine area. As long as your above 5.5, you should be ok. 36 tons over 10 acres, you should be just fine by now.
